Hi y'all,

I posted this here, because i am hoping it will get the most traffic. I'm pretty savvy when it comes to finding stuff on the internet, however i hit a brick wall with this one. I would like to restore the factory brake booster that goes on ny 67 barracuda. Mine wasnt originally power brakes. This booster was taken from another 67 A body car, and i want to put it on mine.

Anybody know of a source making seal and diaphragm kits for the OEM boosters? Not a guess on this place or that place may have it. I been thru the internet already, and came up empty.

Thanks
Matt
 
From what I understand they take some specialty stuf to rebuild. I'm not sure why because it seems fairly simple. You can have yours sent out and rebuilt, but I've never seen components for them for sale to rebuild it yourself.
 
Me either!

I got a NOS unit from a member on this site. Nice piece with the shiny factory finish, but it must have set for too many years (obviously) as it has a vacuum leak under light pedal pressure. I gave up on finding rebuild pieces and got a RamMan rebuild from another member. While it works just fine the re-finish from this vendor is poor compared to a factory unit! I still hope to find a kit to fix the NOS unit as it looks to darn nice!
 
could you take the reman apart and cannibalize the parts for the OEM case? My FSM for my 57 Fors showed the booster as a serviceable piece. Just a bunch of O-rings?

Sure, but if it went wrong then now there is 2 bad units. Guess I should consider it this off season!

Appears to me the reaction seal on the pedal side is not sealing good under light pressure, seems simple but we all now how good intentions can turn bad.
 
youtube has a few vids on Bendix booster rebuilds. Seems the hard part is the disassembly of the tabbed versions: some bolt up, some have V-bands. You need to put it under a press, and clock the 2 shells under a good amount of pressure to locate the tabs and then twist-lock them (imagine 2 huge tanks sender ring wrenches on the 2 shells) or set the tabs with a drift. But it looks very simple inside. Chevy used Bendix too so the parts may cross. Seems rebuilders exchange these for fast turnarounds.

here, 67 Bendix rebuild kit...for a Caddy! $117...not much cheaper than a reman?

I had an oldsmobile booster i put in my old 60 el camino when i was converting it to power brakes, i had to cut the rod going to the pedal and thread it for a heim joint. The 59-64 chevy pass car used a booster bracket setup like our a bodies that raises the booster up on the outside of the firewall. I found a 59 chevy booster bracket at the junkyard, but no booster. Thats why i used a late model olds cutlass one.

Ultimately i had to shorten the rod and use a heim joint. It was a twist to lock booster with the tabs. Wasnt very hard to dissassemble at all, then i shortened the rod, reassembled the assembly, checked it to make sure it held vacuum, it worked fine.

Both of my mopar ones are v band type. One is a 67, the other is a 74. These things are not complicated. I just need a kit. If booster dewey is rebuilding these, then he is getting a kit from somewhere.
 
Perhaps the 1 piece you need is available once you get in there and determine where its leaking. looks like the Diaphragm itself is the main component.
 
67-69 and beyhond A-bodies use the Midland/Ross piece. Has a clamp to seperate the unit. Does not look to hard to repair. I forgot I have another, the original. It sat 25 years and the case is painted black but the guts may still be good?
 
Round file that boat anchor. We don't need them on a-bodies. They just make for a spongy experience.
 
I took apart 2 Midland-Ross boosters (V-band, easy), one on my 1965 Newport and the other from a 1974 Dart slant. Both were the same diameter shell, but parts didn't interchange. The 65 had a rotted thru rubber diaphragm, right where the vacuum port sits, even though I had installed a charcoal filter in the hose to keep gas fumes from the intake out. I wanted to swap the 65 baseplate to the 74 booster to get the correct 4-bolt pattern for my 65's firewall plate. But, the diameter of the aft piston (slides thru baseplate) differed. Otherwise, internal parts were similar. So, even boosters w/ the same nominal dimensions don't always interchange. BTW, the booster on the Newport was a rebuild via an auto parts, so might have differed from factory 65.
 
Reman incorporated. Sells them $138. Remaninc.com lots of hard to find brake stuff on there sight.
